Shuttle conversion for Browning1918 Belt Filling Machine
The bobbins (shuttles) are manufactured in 316L stainless steel, the shuttle base (body) is Carbon Fiber-Nylon composite with exceptional toughness and abrasion resistance, the shuttle will come with a new shoulder bolt for your belt cover.
These conversions are non-destructive and will function with your existing L-arm without the need to trim it (so you can always go back to the needles)
